About LDH Kalibrierservice GmbH
LDH Kalibrierservice GmbH was founded in April 2012 in Dresden and took over a calibration laboratory that had been active in the market for more than 25 years. The owner-managed company operates a DAkkS-accredited calibration laboratory (D-K-18673-01-00) according to DIN EN ISO/IEC 17025:2018 for more than 16 measurands. Calibration is performed manufacturer-independently in the fields of electrical measurands, time and frequency, temperature and humidity, dimensional and mechanical measurands, vibration, acoustics, optics and telecommunications – as DAkkS calibration, factory calibration, on-site calibration or customer-specific calibration. In addition, the company offers adjustment, repair, measuring equipment management, MSA/measuring equipment capability studies, training as well as a pick-up and delivery service. On 816 m² of climate-controlled laboratory and office space, 18 employees work with modern reference standard technology, including from FLUKE, and in-house software development for automated calibration routines and certificate creation. Since 2023, LDH has been a full member of the German Calibration Service (DKD).
